Abstract

The invention discloses a self-cleaning antibiosis leather coating. The coating comprises, by weight, 2-3 parts of poly(epsilon-caprolaclone glycol), 0.2-0.4 parts of diphenylimidazoline, 0.1-0.2 parts of Salatrim, 1.7-2 parts of polyvinylpyrrolidone, 0.8-1 part of polyacrylamide, 1.6-2 parts of stannous chloride, 0.1-0.13 parts of triethanolamine, 190-200 parts of methyl methacrylate, 3-4 parts of sodium dodecyl sulfate, 0.1-0.2 parts of urotropine, 0.2-0.3 parts of ammonium persulfate, 6-7 parts of a 20-25% formaldehyde solution, 16-20 parts of zinc acetate, 4-7 parts of silver nitrate, 0.2-0.5 parts of dithiosalicylic acid, 1-2 parts of calcium propionate, 0.1-0.3 parts of aluminum magnesium silicate, 0.7-1 part of hexamethylphosphoramide and 0.07-0.1 parts of iron trichloride. The coating has the advantages of antibiosis and excellent water vapor permeability, and leather coated with an emulsion obtained by using the coating has good antibiosis and excellent health performance.

Description

Technical field [0001] The invention relates to the technical field of leather coatings, in particular to a self-cleaning antibacterial leather coating and a preparation method thereof. Background technique [0002] Leather finishing agent / textile coating agent is a polymer compound that is uniformly coated on the leather / textile surface. It forms one or more films on the leather / fabric surface through adhesion. Therefore, the quality of the coating material not only directly affects the appearance and quality of the product, but also determines the performance of the product to a large extent. Polyacrylate emulsion has the characteristics of film-forming flexibility, flexibility, light resistance, aging resistance, and moisture resistance. It is a type of leather textile coating material widely used at present. However, the existence of some polar groups in traditional polyacrylate emulsions and the impact of environmental conditions during storage, transportation and use of p...
